' Application filed July 19, 1906. Serial No. 326,905. I

To all whom it may concern.-

Be it known that I, EDWARD F. CAMERON, a citizen of the United States,residing at Helena, in the county of Lewis and Clark and State ofMontana, have invented certain new and useful Im rovements inWeed-Exterminators and I herebcy declare the following to be a full,clear, an

- ing noxious weeds and destroying parasites,

and comprises a tube having a nozzle at one end, through which aneedle-valve projects, and in the provision of a knife having an angledcutting edge and ribbed to allow the liquid which is dispensed from thetube to pass throu h an aperture in the knife and upon the p ant whichhas been severed by the knife.

The invention comprises various other details of construction andcombinations and arrangements of parts, which will be hereinafter fullydescribed and then specifically defined in the appended claims.

I illustrate my invention in the accompanying drawings, in which- Figure1 is a central longitudlnal sectional view through my invention. Fig. 2is an enlarged detail view of the nozzle. Fig. 3 is a front elevation ofthe nozzle. Fig. 4 is a cross-sectional view on line 4 4 of Fig. 1, andFig. 5 is a top plan view of the nozzle.

Reference now being had to the details of the drawings by letter, Adesignates a tube,

which may be of any size or len th and has a portion thereof tapered, asat C designates a nozzle which is fastened .to saidtube and taperscontinuously with the tapering ortion of the latter and terminates in apoint Q having a minute opehing through which the needle-point D at theend of the rod D passes. The opposite end of the tube is provided with athreaded plug E, and interposed between said plug and the end of thetube is a suitable washer F, adapted to make the joint tight to preventany eakage therefrom. H designates a handhold which is fastened to theend of the tube to which said plug is fastened. Said plug is centrallyapertured to receive the rod D and is provided with 9.

kn? K, having threaded connection therewit L designates a disk which isfixed to the rod D, and O is a coil-s ring interposed between said diskL and t e washer F, serving normally to hold the nozzle closed. Qdesignates a threaded plug utilized as a closure to afilling-aperturewhereby poisonous liquid may be cured into the tube. N designates adiskw 'ch is fastened to the inner tapering wall of the tube and serves as avalve-scat. R designates an elastic valve which is held by the threadeddisks S and S upon the rod D. T designates a knife which is secured tosaid nozzle, and a portion of said knife, which is angular, projectsbeyond the end of the nozzle. Said knife, which has an angled cuttingedge, is preferably longitudinally troughed and is provided with anopening '1" in the bottom of the trough a short distance from the angledcutting end thereof. A curved guard T rises from the up er surface ofthe knife and is adjacent to tile forward marginal edge of the opening Tand is disposed at an inclination to said knife, the object of saidguard being to deflect the liquid which is dispensed from the nozzle andcause the same to run through the opening T upon the weed which has beensevered by the cutting edge of the knife. It will be noted that theunder edge of said opening is countersunken for the purpose ofpreventing the hole being easily clogged up.

In operation the device should be held at an inclination, preferablyforty-five degrees, and the cutting edge of the knife be insertedunderneath the surface of the ground and caused to sever the root of theweed adjacent to the surface of the ground, the shield pushing back thetop of the weed and protecting the hole in the knife. This brings thetop of the root immediately under the hole. The knob at the end of therod is then drawn up slightly with the fingers of the operator and a fewdrops of the liquid dispensed, which, striking the shield, will bedeflected thereby through the hole in the knife directly upon thesevered root without the poisonous liquid coming in contact with thegrass about the weed.

From the foregoing it will be noted that by the provision of the deviceshown and described a simple and efiicient means is afforded foreffectually killing weeds, parasites, &c., by the simple cutting of theroot and applying the poisonous liquid thereto ed within said tube andprovided with a neewithout in any way affecting the surrounding bladesof grass.

' What I claim isx 1. A device for destroying noxious weeds andexterminating parasites, comprising a tube having a nozzle, a movablerod mountdle-valve extending through said nozzle, an apertured knifefixed to said nozzle, and a guard for deflecting the liquid dispensedfrom the nozzle, causing the same to pass through the aperture-of saidknife, as set forth.

2. A device for destroying noxious weeds and exterminating parasites,com rising a tube having a nozzle, a movable ro mounted within said tubeand provided with anecdle-valve extending through .said -nozzl e, -an"angled'knife fixed to said nozzle and; project-1' ing beyond the endthereof, the upper surfaceof said knife being troughed and aperturedadjacent to its end, the under marginal edge of the aperture beingcountersunken, and a guard rising from the upper face of the knife 4adjacent to said aperture, as set forth.

3. An apparatus for exterlninating Weeds, comprising a tube havinganozzle, a rod mounted within said tube and having a needle-pointextending through the nozzle, a valve-seat within the tapering portionof the tube, a valve mounted upon said rod and adapted to contact withsaid seat, a disk fixed to said "rod, athreaded plug at the end of thetube and through which said rod passes, a spring interposed between saiddisk and plug, a knife fixed to the nozzle, and a guard rising adjacentto the marginal edge of an opening in. said knife, as set forth.

4. An apparatus for exterminating weeds,.

.with the end of said rod, a handhold upon the tube, an angled knifefixed to said nozzle g in'al edge of which is countersunken, a curvedguard rising from the knife adjacent to the marginal edge of saidaperture, asset forth.

, In testimony whereof I hereunto affix my signature in thepresenceoftwo witnesses.
